•Extra-large porous Rh@MIL-101 has been prepared with an improved procedure.•The catalyst was tested in the hydroformylation of different olefins.•High activity and selectivity to n-aldehydes are achieved.•Large olefins and especially internal alkenes are very slowly converted.•Rh proposed to be located at less accessible supertetrahedral units of the walls.
Highly porous and crystalline metal–organic framework MIL-101 has been synthesized and used for the preparation of rhodium supported catalyst. Acetylacetonato(1,5-cyclooctadiene)rhodium(I) has been used as catalyst precursor. The material has been characterized by XRD, XPS, SAXS, FTIR, SEM, TEM, AAS, and nitrogen adsorption. The catalytic properties of Rh@MIL-101 have been investigated in the hydroformylation of olefins with different structure and chain length to the corresponding aldehydes. High conversion and selectivity to n-aldehydes have been achieved in the hydroformylation of n-alk-1-enes. The obtained results show that the rhodium species are highly dispersed and preferentially located at internal and less accessible sites at the supertetrahedral units.
